Refractory Foam Zirconia Ceramic Filter for Molten Steel Filtration

Zirconia ceramic foam filter is a porous material with a high-temperature properties, its diameter from the nanometer to the micron range, porosity is from 20% to 95%, and the use of a temperature can reach up to 1600° C. Zirconia ceramic foam filter can be made by specific procedures and have peculiar bone-frame holes just like the shape of foam (called three-dimensional connected channel) and myriad eyelets which only been found in big times microscope. The three-dimensional structure can improve the cast quality in large scale by changing the molten metal from turbulence flow to lamellar flow, removing the gas and smoothing the casting. Ceramic foam filter is not only applied for molten metal filtering in high temperature, but gas treatment in high temperature, carrier of catalyzer, solid heat exchange and advanced filling for chemical industry compare to similar ones.
